Structural Formula：

Standard：

Properties：It is a colorless and transparent liquid. Density(25℃): 0.953g/cm³, Refractive index (25℃): 1.408, Boiling point: 228-229℃, Flash point: 24℃.

Uses：Tris (trimethylsilyl)phosphate is mainly used as an additive in lithium-ion battery electrolyte. It can form a dense, silicon-phosphorus-rich solid electrolyte interface film on the surface of high-voltage (≥ 4.3V) cathode materials, thereby significantly improving the low-temperature performance and normal-temperature cycling performance of lithium batteries.

Storage：This product should be stored in a sealed container protected by nitrogen and kept in a cool, well-ventilated and dry place. Keep away from heat sources and fire sources, and avoid exposure to light.

Packing：200kg stainless steel drum with quick couplings and protected by nitrogen.
